clickhouse.com is built on a warm, off-white canvas (rgb(250, 255, 105)).
The system uses rgb(22, 101, 52) as the singular interactive color.
Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside __Inter_d1b8ee as the primary typeface.
A layered elevation system (6 distinct shadows) building a clear front-to-back hierarchy.
Motion is a first-class concern — 7 keyframe animations plus transition-driven interactions.

18 enforceable rules pulled verbatim from the spec
Do
Use #faff69 (`#faff69`) as the page background — it's intentionally not pure white
Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
Use #166534 (`#166534`) as the primary accent — it's the brand's signature interactive color
Use 8px border-radius on buttons — the standard corner rounding for interactive elements
Use 8px border-radius on cards — consistent with the grid card corners
Maintain nav height at 40px — consistent vertical space for the navigation bar
Transition button background to #14532d (`#14532d`) on hover — this is the extracted interactive state
Each card includes a top image — imagery is part of the card identity, not optional
Use a 5-column grid on desktop — density matters for this content type
Use expandable accordion for the FAQ — saves vertical space and lets users self-navigate
Don't
Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity
Don't invent new shadow values — use only the extracted shadow levels
Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements
Don't introduce additional saturated accent colors — the palette is intentionally controlled
Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
Don't use opacity or brightness filter for button hover — the design uses an explicit background color change
Don't make the nav sticky — this design lets it scroll away to maximize content focus
